      Core Concept

      Introduction to Laravel

      Laravel is a web application development framework based on the PHP programming language. It is an open-source framework designed to make it easy for developers to build high-quality web applications quickly and efficiently.

      Laravel provides a rich set of features that simplify the development process and allow developers to focus on the core functionality of their applications. The framework is well-suited for both novice users in the world of web development and experts in the field of development.

      Laravel is a PHP web framework that provides capabilities for building modern, full-stack web applications.

      It is an open-source framework, and its document is available at https://www.laravel.com/

      Preference for Laravel

      In the ever-moving technology landscape, numerous frameworks come into the market. In this section of the chapter, we will explore what makes Laravel unique and stand out among other frameworks for application development.

      Scalable

      PHP is a scalable language, and Laravel provides built-in support for fast, distributed cache systems like Redis, making the framework support horizontal scalability. Laravel applications in the past have been able to scale to handle hundreds of millions of requests per month.

      Laravel platforms, such as Laravel Vapor, provide serverless capabilities for Laravel development. It is powered with Amazon Web Services ( AWS) and makes including capabilities of AWS in Laravel development easy and maintainable.

      MVC Architecture

      The Laravel framework is based on the Model-View-Controller pattern (MVC pattern), which makes the application’s business logic and presentation to be distinct, making the framework powerful by increasing its performance. This concept is discussed in-depth in Chapter 2, MVC Architecture in Laravel, In this book.

      Community

      Laravel has a robust and active community. The project is open-source and has active contributors, discussion forums, and a strong developer community. The strength of the Laravel community enables new developers of the framework to find good documentation and makes it easy for them to learn and develop using Laravel. Additionally, Laravel is adopted by many developers, leading to increased demand and support in case of issues during development. This lowers the barrier to entry for novice developers and fosters a welcoming and supportive environment.

      Class Dependency Management

      Laravel framework is powered by the Inversion of Control Container (IoC Container), which enables class dependency management. It makes the framework powerful by its capability to automatically resolve classes without configuration.

      The dependencies are tackled at runtime, which allows flexibility as dependency implementations can be swapped easily. The two ways in which the IoC container can resolve dependencies are Closure callbacks and automatic resolution.

      Eloquent ORM

      Laravel framework enables Eloquent Object-Relational Mapping (ORM), allowing Laravel developers to write with PHP syntax over SQL syntax. It provides a great and optimal way of implementation of ActiveRecord for working with one’s application database. Eloquent ORM is explored more in Chapter 5, Working with Eloquent ORM and Query Builder, of the book.

      Laravel is a powerful, robust, and developer-friendly framework, providing modern capabilities to develop applications. Figure 1.1 highlights the key pillars of Laravel that make developers prefer it.

      Figure 1.1: Laravel Key Pillars

      Laravel also provides the following capabilities:

      URL Routing Configuration

      This enables viewing the content of a link in the same webpage instead of redirecting to the link. With Laravel’s built-in file configuration, it is loaded with the framework and provides a seamless experience for the application user.

      Mail Service

      Laravel has the Swiftmailer library, which enables clean and straightforward API configurations for individual email accounts. It provides drivers to permit message sending via cloud-based and local services.

      Some of the drivers include SMTP, Mailgun, Mandrill, SparkPost, PHP’s mail and Sendmail functions, and Amazon SES.

      Message Queue System

      Laravel enables and powers the message queue system with its own built-in queue system, which is a simple API capable of running tasks in the background. It also supports message queues like Redis, SQS, and many more.

      Scheduling

      Laravel provides the capability to custom schedule tasks and jobs without requiring the developer to set it up at the system level. The Laravel CRON job is Laravel’s built-in utility that provides scheduling functionality in a user-friendly way.

      Authentication and Authorization

      The key factor that makes the Laravel framework loved by developers is the ability to enable easy control access to resources and organize authentication logic.

      Laravel site owners can seamlessly streamline authentication, and the framework provides the owners with flexibility and security when dealing with authorization and authentication.

      Unique Features of Laravel

      Laravel is widely adopted across the developer ecosystem and has become the go-to framework for developers for their application development. What makes Laravel unique are its several diverse features. Let’s explore these unique features of Laravel.

      Database Seeding

      The Laravel framework has the ability to populate the database tables with seed data using seed classes. These seed classes are stored in the database/seeders directory, with a default DatabaseSeeder class defined.

      This class can be modified to the application’s requirement.

      Let’s write an example of the DatabaseSeeder class to add plants and their species name:

      namespace Database\Seeders;

      use Illuminate\Database\Seeder;

      use Illuminate\Support\Facades\DB;

      use Illuminate\Support\Str;

      class DatabaseSeeder extends Seeder

      {

      /**

      * Run the database seeders.

      */

      public function run(): void

      {

      DB::table(‘plants’)->insert([

      ‘name’ => Str::random(10),

      ‘species’ => Str::random(10)

      ]);

      }

      }

      Localization

      With globalization and to accommodate users across the globe with different languages, Laravel provides the localization feature, enabling the retrieval of strings in different languages. This allows the Laravel application to support multiple languages within the Laravel application.

      There are two ways to achieve translation strings:

      langdirectory

      The language strings must be stored in the lang directory. There is also support to include subdirectories for each language supported by the application. Through this feature, Laravel can manage translation strings for built-in features, such as validation error messages.

      /lang

      /en

      messages.php

      /es

      messages.php

      JSON files

      Translation strings can also be placed within JSON files, which must be stored in the lang directory structure. In this approach, each of the application’s supported languages will be in a separate JSON file, which will be listed under the lang directory.

      When dealing with a large number of translation strings, this method must be preferred.

      /lang

      en.json

      es.json

      Configuring the locale is also trivial in this case. By default, the application’s default language is stored in the config/app.php configuration file under the locale configuration option.

      The default language can be modified for a single HTTP request at runtime with the setLocale method of the App facade.

      use Illuminate\Support\Facades\App;

      Route::get(‘/greeting/{locale}’, function (string $locale) {

      if (! in_array($locale, [‘en’, ‘es’])) {

      abort(400);

      }

      App::setLocale($locale);

      // …

      });

      It is also a good practice to configure a fallback language. This should be configured in the config/app.php configuration file.

      The syntax to set a fallback language is as follows:

      ‘falback_locale’ => ‘’

      An example, to set the fallback language as English:

      ‘falback_locale’ => ‘en’

      To determine the current locale, the currentLocale and isLocale methods can be used, as follows:

      use Illuminate\Support\Facades\App;

      $locale = App::currentLocale();

      if (App::isLocale(‘es’)) {

      // …

      }

      Latest Version Release Changes

      Laravel 10 is the current Laravel version in use. If you already have a previous version of Laravel, you can continue to upgrade it. Alternatively, if you are new, follow the next section of the chapter on how to install Laravel.

      How to Upgrade

      In order to upgrade any existing Laravel projects to Laravel 10, updating the dependencies is the most crucial step. The documentation for the upgrade is available at https://laravel.com/docs/10.x/upgrade

      Let’s explore how to upgrade to Laravel 10 to get the latest features and make the necessary changes to upgrade our existing Laravel applications.

      Dependencies

      Laravel requires PHP 8.1.0 or higher and Composer version 2.20 or higher.

      The following dependencies need to be upgraded in the Laravel applications composer.json file:

      Table 1.1: composer.json dependencies for Laravel 10

      Additionally, if you wish to use PHPUnit 10, then delete the processUncoveredFiles attribute from the section of phpunit.xml, and update the following in the composer.json
